I .To all 'whom z't maf/ t'oncem:

' We it known that. AUGUSTUS Bowsnn, de-` ceased, formerly residing at FortfzWayne, in the county of Allen and State of Indiana, did invent certain new and useful Improvements in Liquid-Dispensing Apparatus, of which the followin is a specification.

This inventon re ates to nnprovements in liquid dispensing apparatus and the object thereof is to afl'ord facil-ities' by means of which gasolene and oils or other vliquids may be dispensed in definite quantities without the nece'ssity of Operating a pump.

'The 'object of the invention is accomplished by the construction illustrated in .theaccompanying drawings, in which Figure 1 is an elevation showing a general arrangement lof parts'constituting a complete' installation, portions being cut away and in section;

F 2 is a side elevation in Vertical sec- .tion showing, a dispensing head, portions being cutaway; i

liquidi and 2 'istan auxil'iary Figure 3 is atransverse section of Figure `l2 on the line H thereof;

Figura 4 is a'detail view elevation' of a portion of a dispensing head;

vFigure 5 is a Vertical section 'through a part ofthe supporting stand for the head, the plane being at right angles to that of Figure 4, showing a by-pass valve arranged in connection with the supply-pi e and showing' also the Operating lever or the valve; and Figure 6 is a detail view showing thev bypass Valve aranged in connection with the supply-pipe and overflow pipe and showing also thev Operating leVer, a portion of the view being in Vertical section.

Similar numerals 'of reference indicate correspondin parts throughout the several views and re erring now to the 'same:-

1 is a reservoir for holding a supply of' situated in a p ane lower than the 'reservgjin A. ventpi-pe3 has communicationwith the reservoir showing a front at the 'top thereof, and a' discharge pipe ex- I tnds into the 'a foot-valve 5 at itslower end. j 'A fill-pipe 6 top thereof and reservoir and is provided with has communication witli'tlie reservoir at the through which the reservoir is recharged, therebeing an extension 6' connected with the fill-'pipe proper. A drain- .pipe 7 'has comm ication with lthe fill-pipe 1921. erial R0. 439,881.

l6 and is used for the return of surplus liquid.

A discharge pipel 8 extends into the aux- 'iliary tank and has communication with the lower part thereof, and has connection with its upper end an air-pipe 13 through which zur-pressure is applied for expelling liquid from the tank, the liquid passing out through the disc-hargepipe and check-Valve; 11 into the sup ly-pipe 10 when the -pressureisapplied. he-pipe 13 also serves as anexhaust pipe when the tank is being refilled The air is applied and exhausted throu h the medium of va controlling mechanism ing connection with the air-pipe' 13. The controlling mechanism is comprised of a manifold 14 having communication with the air-pipe 13 and also with an exhaust pipe 15 through an escape-valve 16; An air supply pipe 17 has communication with the manifold through a throttle-valve 18. I The' throttle-valve and the escape-Valve 'are operated simultaneously by a lever 19 which is actuated by means vof an electro-magnet 20. The' exhaust-pipe may, if so' desired, be connected with the. Vent-'pipe 3 so that the' latter will convey the discharge. B and C are discharge heads through which the liquid is 'dispensed, andexhaust to its final "mov terial to the `present invention asiany other suitable meter may be employed instead of'` of the dispensing heads that shown Each is `comprised of a supportin stand 21 upon the top of which is supports a vessel 22 the `Vertical-v'valls of which are of transparent' material, such as lass. `The vessel has a supply-pipe 23 lea` ing from its bottom and .1,

is pivotally through'the medium of suitable T-connec-v4 tions 27.

In the front of the stand is av chambered '15 protuberance` 28 having a lid 29 for closing the same, and the latter has a fiange 30 extending outwardly with a lid 31 hinged thereto. A push-button 32 is 'mounted with its stem extending through the lid 29 so as 20 to engage an operating lever 33, the latter having bearing connection against the stem 34 of the valve 24. A pin 35 also is slidably `mounted in the lid 29 with its inner end bearing against an Operating lever 36 which mountedand has also bearing relation against the stem 36 of the by-pass valve 26. The pin 35 is so proportioned that -when the lid 31 is in closed position the valve 26 willV be held openl through the me- 30' dium of the lever 36 and the pin 35,' thus permittin pass out-t rough the upper part of the supply-pipe 23 and the by-pass valve into the overflow pipe. Also the lid 31 incloses the 35 push-button 32 so that it may not be operated without opening the lid.

A conduit 37 extends up through the stand 21 and leads to the magnet 20 and contains wires 38 for exciting the magnet and 40. for supplying a lamp 39 at the top of the dispcnsing head. An electrical switch 40 ,is arranged in connection with the conduit and is adapted to`be closed'by a plug 41 that is mounted upon the operating'lever 33 when the latteris pressed lnwardly by applyingpressure to the push-button 32. A baflle-disk 42 is mounted within the lower part of the vessel 22 over the upperend of the supply-pipe 23 and is for the purpose of causing the liquid to rise evenly as the vessel is being filled. A discharge nozzle 43 has communication 'with the lower end of the vessel 22 throughl which the liquid is finally dis nsed.

t is the intention that the electrical wires will have connection with a suitable source of energy, and the pipe` 17 will have connection with a suitable source of air under pressure. The pipe 44 communicating with 00 the lowerpart of the auxiliary tank 2 is used-for the purpose of extracting foreign matter that may accumulate in the bottom of the tank.

- In' theoperation L ervoir is 'charged of the invention the resthrough the fill-pipe 6;'

e stand is a by-pass valve 26 connecting.

the content of the vessel 22 tov and also the tank 2 and the siphon are initially filled through the pipe 12. zBy pressing upon the push-button 32 the switch 40 is closed and the valve 24 is opened through the medium of the lever 33 so that the magnet becomes excited with the effect that the lever 19 becomes drawn upwardly, which i movement opens the air-valve 218 and permits the exhaust-valve 16 to close. Thus, air-pressure enters though the pipe 13 into the tank 2, which forces the liquid c'on-` ,I tain'ed therein out through the discharge pipe 8,- the supply-pipes 10 and 23,,into the vessel. 22. This operation is continued until the vessel is filled to the level of the overflow pipe opening. The push-button is then released, the .switch thereby is opened andV the. valve 24 is closed. Any surplus liquid' flows down through the overflow pipe 25 and is carried back' to the fill-pipe 6 through the pipe 7. When the switch is opened the magnet 20 drops to its normal position, together with the lever'19, causing'the airvalve 18 to close and the exhaust-valve 16 to open, so that the air introduced into the tank 2 is released and discharged through the exhaust-pipe 15. When thus released of air-pressure the tank becomes automatically refilled through the siphon. The liquid contents of the vessel is then dispensed through the nozzle 43 in such quantities as desired." The Vertical walls of the vessel, being of glass, admits observation of the liquid as it enters the vessel and as .it is removed therefrom, and the patron is thus permitted to ascertain the quantity of liquid purchased.

When the operation o f the apparatus is to be temporarily suspended, the lid` 31 is closed and locked thusI concealing the pushbutton, and the by-pass valve is thereby held open by the pressure of the door against the pin 35 which actuates the valve through the medium of the lever 36.y The contents of the vessel thereby is permitted lto drain through the feed-pipe and valve into the overflow pipe 25. i
